Junfang Tian · Journal of Networks · 2014
In order to solve game-theory model problem based on carrier sense multiple access protocol with collision avoidance in wireless network, a game-theory-based general and compatible modeling process is proposed, where the transmission probability of a node in a slot time is regarded as mixed game and network performance parameter M is taken as revenue function of game so as to build M rounds non-cooperative mixed strategy game with N gamers. After performing M rounds game, it will acquire M Nash-equilibria which is not equal to each other, and then these Nash-equilibria are taken as the input of single objective programming model with many constraints so as to obtain compromise equilibria. Finally, a minimum contention window based on compromise equilibria is designed. The throughput and successful transmission rate are analyzed through the simulation, and the simulation experiment results show our proposed modeling process has the more throughputs and the lower drop performance than the existing methods.
